Harbour Energy's Five-Day Buyback Activity Across XLON, BATE, CHIX, AQXE and TRQX

During the reporting period, Harbour Energy executed purchases across five regulated trading venues: the London Stock Exchange (XLON), Cboe BXE (BATE), Cboe CXE (CHIX), Aquis Exchange (AQXE), and Turquoise (TRQX). The highest price paid on any single day was £3.0300 per share on 2 November 2026, recorded on TRQX, while the lowest price paid across the entire period was £2.6080 per share on 6 November 2026 on CHIX. This spread of venues reflects standard market practice for large buyback programmes, allowing execution across fragmented UK equity markets to minimise market impact. Barclays acted as the executing broker on the company's behalf.

Daily Share Purchase Volumes and Price Trends During the Reporting Period

Across the five trading days, purchasing activity was heaviest on 2 November 2026, with the London Stock Exchange alone accounting for 680,076 shares at a volume-weighted average price of £2.9446. Volume-weighted average prices declined progressively through the week, falling from the mid-£2.90s on 2 November to the mid-£2.60s by 6 November 2026. The company did not disclose the aggregate daily spend for each session, nor the total cash deployed across the full reporting period in this announcement. All purchased shares are being cancelled rather than held in treasury, which directly reduces the company's total issued share capital.
